[Intl_DxMedPhys] Barco 32 MP mammo monitor

[Douglas Pfeiffer]

I’d have to think it through more (thinking is hard on a Friday), but one benefit of the smaller pixel size is that it would possible to see a larger field of view at full resolution. 5 MP makes that possible with current systems, but it’s possible, I guess, that future systems could possibly have smaller pixels to require the monitor to be equivalent.

Best regards,
Doug

Quoting the ACR-AAPM-SIIM "The finer pitch will not improve the spatial resolution of the underlying image data, which is determined by the imaging system, and the benefits over a pixel pitch of 0.200 mm are negligible at a viewing distance of 60 cm because of the limitations of the human visual system discussed earlier. However, the larger array size allows for viewing a larger region of the mammography image at the native, or full, resolution (ie, 100% zoom, no interpolation)."
